People do not fall off cruise ships.
You have to be seven feet tall or do something pretty dumb to fall over a railing.
Yes: If you lean over REALLY FAR or get up on a chair to get a better look then you could "fall" overboard.
People who "fall" off cruise ships are either doing something they aren't supposed to be doing or they jump.
I'm sorry for those who have gone over but they weren't standing by the railing and suddenly they slipped and were flung overboard.
I'm just waiting for the day they enclose the balconies with chain link fencing to prevent the abuse.
